UNITED STATES PATENT OFFICE HENRY SCHNEIDER, OF CHICAGO, ILLINOIS.

WINDOW-CLEANER.

Specification of Letters Patent.

Patented Nov. 21', 191e.

Application filed November 1 1,` 1915. Serial No. 60,858.

To all 'whom it may] concern Beit known that I, HENRY SCHNEIDER, acitizen of the United States of America, and a resident of Chicago,county of Cook, and State of Illinois, have invented certain new. anduseful .Improvements in IVindow- Cleaners, of which the following is aspecication.

The 4main objects of this invention are to provide an improved form ofwindow cleaner and particularly one which is'specially adaptedfor'use onthe motormanls window of-a street car; and to provide a window cleanerthat is simple and durable and that can be readily attached to thewindow l'frame of any car without altering the construction of eitherthe frame or the sash. An illustrative embodiment of this invention isshown in the accompanying drawings, in which: Figure 1 is a frontelevation of a street car body with lthe improved window cleanerfastened in lposition on-the .frame of Y the motormans window. Fig. 2 isaA front elevation of the cleaner drawn on a larger scale. Fig. 3 is a.fragmentary detail showing the' supporting mechanism for one end of thesqueegee. Fig.. 4 is a view taken on the line A--A of Fig. 3.

In the construction shown in 'the drawings thewindow frame '-1' of astreet car 2 is 'shown provided with the improved cleaner `attachedadjacent to the4 sill thereof. The cleaner comprises a pair of supports4 which The operation of the device shown is as follows z-In order toclean the Window the operator need merely lower the window and return itto its closed position. The squeegee requires no attention and operatesto wipe the window both -in its downward and its vupward movement,regardless ofwhat may be the particular arrangement for raising andlowering the window. The springs y 9' urge the sq'ueegee into contactwith the window paneat all times, and the 'pins 9 squeegee to follow thewindow in case the arrangement is such as to require the window to beshifted out lof its normal plane and bifurcated guide members 7 permitthe for the purpose of lowering it. The heads or shoulders at vthe outerends", ofthe pins l0 limit the movement of the squeegee in its guides,so that it cannot become accidentally may be readily attached by screwsto the pivotal movement in an upward direction against the action ofsprings 12acting between pins 13 on the supports 4 and pins 14 on lowerarms 7 of the guide members 5. Movement of the guide members anddisengaged therefrom.

In certain window, constructions which are now in common use on streetcars, the lower edge of the window rests in a grooved ledge on the sillwhen the window is in its closed position and the sill is provided witha pocket rearward of this groove into which the window sash may belowered for the purpose of opening the window, such pocket beingnormally closed by la hinged sill section which in its closed positionbears against the lower part of the window sash and locks thesame in itsclosed position.

The action of the squeegee is suchtliat i the window is wiped asit-descendsinto the pocket and is again wiped as it is liftedfrom thepocket. During the\ operation of lifting the window and sliding itforward to its closed position, the squeegee swings upward and slides inthe bifurcated guides, but

is held into contact with the window by the springs 12 and 9, as will bereadily seen -from a consideration of the drawings.

squeegee in a' downward direction is limited by pins 15 on the supports4,

Although but one specific embodiment of this invention has been hereinshownl and described, it will be understood that some of the details ofthe construction shown may be altered or omitted without departing" fromthe spirit of this invention as defined by the following claims.

I claim: .Y l 1. A window cleaner, lcomprising supports, bifurcatedguide members pivotally mounted on said supports, yielding means forresisting pivotal movement of said guide members, a squeegee slidablymounted on I said guide members-,and a spring beziring Y between saidsupport andsqueegee for shift-v pivotal movement of Said guide members,a

squeegee mounted in said guide members, a,

pin mounted on said squegee sind passingpin for through a 111g on saidsupport, a spring surrounding said pin and bearing between said Asqueegee and lug'for shifting said squeegee.

in saidA guide members, Vand means on said limiting the movement of saidsqueegee. E f Signed" at Chicago this 27th day of Oct.;
